ALBERT S. BUTNER, OF HIGHLAND, KANSAS.

GRAIN-COVER.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed May 9, 1907. Serial No. 372,723.

To all whom it may concern.

Be it known that I, ALBERT S. BUTNER, citizen of the United States,residing at Highland, in the county of Doniphan and State of Kansas,have invented certain new and useful Improvements in Grain-Covers, ofwhich the following is specification.

The present invention relates to an improved device for sheltering grainand protecting the same from the elements while stacked in an openfield.

The object of the invention is to provide a simple and efficient deviceof this character which can be readily transported from place to placeand quickly applied to the stack.

A further object is to so construct the cover that it can be raised andlowered to accommodate itself to various heights of the stack.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction of the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a perspective view of the improved grain shelter, a portionof the cover being removed; Fig. 2 is a longitudinal sectional viewthrough the same, portions being broken away; Fig. 8 is a detail view ofone of the U-shaped slips receiving the inner ends of the lateral armsand, Fig. 4 is a similar view of one of the stirrups employed inconnection with the braces.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The numeral 1 designates an upright standard or post which extendsthrough the central portion of the stack which is indicated at tudinalbars 4 having their opposite end portions connected to rmgs 5surrounding the standard 1.

Radiating from the hub 33 are the arms 6:

- the hub 3 and these arms have their inner Slidably mounted upon thisstandard 1 1s a hub 3 comprised of a series of long1- ends received byfastening members such as U-shaped clips 7 at the upper end portions ofthe bars 4. Suitable braces 8 are provided for holding the arms 6 in adistended position, the said braces having the lower faces of theiropposite end portions notched as indicated at 9 to receive the free arms10 of U- shaped stirrups 11 applied, respectively, to the arms 6 andbars 4. It will thus be apparent that the ends of the braces 8 aresecurely held against slipping due to the compression in the said bracesand a rigid structure is thereby obtained.

Specifically describing the method of assembling the various membersconstituting the hub 3 it will be observed that the two rings 5 areeach. formed with a series of openings corresponding to the longitudinalbars 4 and receiving the pins or bolts 15 which extend through thecorresponding bars 4 and engage the respective clips 7 and stirrups 11.With this construction a single pin serves to connect the ring 5 to alongitudinal bar 4 and the corresponding fastening member engagingeither, one of the radial arms 6 or one of the braces 8. A derrick orhay elevator 12 is illustrated as connected to the upper end of theupright 1, and the cable 13 employed for raising and lowering the huband the shelter carried thereby extends around suitable guide membersand is Wound upon a reel 14 upon the said derrick 12.

is claimed as new is:

1. In a grain shelter, the combination of an upright standard, a ringslidable upon the standard, longitudinal bars applied to the ring, clipsapplied to the bars, pins extending through the bars and connecting theclips to the ring, arms radiating outwardly from the standard and havingtheir inner ends received by the clips, braces between the arms and thebars, a covering supported by the arms, and means for adjusting the ringupon the standard.

2. In a grain shelter, the combination of a standard, a pair of spacedrings slidably mounted upon the standard, longitudinal .bars connectingthe spaced rings, fastening members applied to the upper and lowerportion of each of the longitudinal bars, pins ex- IVith thisconstruction, it will be readily apparent that by operating the reel 14,the shelter can be a standard, a pair of spaced rings slidably standard.l

tending through the longitudinal bars and pins passing through the barsand connecting connecting the said fastening members to the the U-shapedclips to the upper ring, a stirrup upper and lower rings respectively,arms raapplied to the lower portion of each of the diating from thestandard and having their bars, a second set of pins passing throughinner ends engaged by the upper fastening the bars and connecting thestirrups to the members, braces for the arms, the said braces lowerring, arms having the ends thereof rebeing engaged by the lowerfasteningmeml ceived by the clips, braces for the arms, the bers, acovering supported by the arms, and said braces being engaged by thestirrups, means for adjusting the rings upon the and a cover supportedby the arms.
